Someone ples

in a party decorations total r balloons were used. there were b blue balloons, twice as many green balloons, and the rest of balloons were yellow. how many yellow balloons were used?

3b - r  

Step-by-step explanation:

b + g + y = r

g = 2b, so

b + 2b + y = r

Combine like terms

3b + y= r

Subtract 3b from each side

y = 3b - r

The number of yellow balloons was 3b - r.

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
